Carbed Magnum parts list?
First, welcome to FABO. Get ready for a lot of opinions.
First check out magnumswap.com, lots of info on oil pan, belts, manifolds etc.
The deal with magnum is, assuming you dont want OD trans, there are two ways to do it.
First is with magnum heads and a "magnum" carb manifold. Second way is with aftermarket magnum heads that are "LA" intake pattern so you can use your LA RPM air gap, Holley etc...
The magnum pattern intake in more expensive and if you already have LA intake you might consider a magnum LA head. The EQ heads are available in both magnum and LA intake pattern. They offer a substantial HP gain over stock heads.
The magnum has so many benefits over LA, 1.6 ratio pedestal rockers, roller cam, closed chamber heads, hypereutectic pistons w molly rings and of course the fact you can pick up a good runner for under $500 that will literally make 450 hp with EQ heads and a cam. We have lots of info on our site too, FAQ section and some write ups and links that help. We also have all the parts you will need to do swap with either carb or FI. magnummopar. or pm for more info.
